What does the Constitution establish?

The Constitution establishes the framework for the government of the United States. It outlines the structure, powers, and responsibilities of the three branches of government: the legislative, executive, and judicial branches. By doing so, it sets the foundation for how the country is governed and how laws are created and enforced. This document is pivotal because it not only defines the roles of these branches but also includes the Bill of Rights, which protects individual liberties.

The other choices focus on specific aspects that are either addressed only partially by the Constitution or fall outside its primary purpose. For instance, while there are provisions related to the military, the Constitution does not primarily define military structure but rather authorizes Congress to raise and support armies. Similarly, the management of international affairs is a function of the executive branch, guided by the Constitution, but the document does not explicitly outline the regulations governing this area. Lastly, the determination of state boundaries is typically managed through state laws and agreements rather than being established within the Constitution itself.
